The bearers (2) in the mould consist of beam components composed of two parallel, long concrete bodies (3,4) in which a longitudinal reinforcement (5,6) runs. Between the bodies there is positioned an intermediary reinforcement (7). - One concrete body (3)of the beam component is cast in or integrated with the intermediary reinforcement and fixed by reinforcements to the concrete plate (1). The intermediary reinforcement is located in a plane at right-angles to the concrete plate, and the other concrete body (4) of the beam component is spaced from the concrete plate.S USE - For casting concrete arches or beams. |
